Comparative performance analysis of LANMAR, LAR1, DYMO and ZRP routing protocols in MANET using Random Waypoint Mobility Model

In this paper, we compare performance of some routing protocols for Mobile Ad-Hoc Networks (MANET´s). A Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile nodes that communicates with each other without using any existing infrastructure or centralized administration. In MANET, due to mobility of nodes network topology changes frequently and thus, routing becomes a challenging task. A variety of routing protocols with varying network conditions are analyzed to find an optimized route from a source to some destination. This paper presents performance comparison of four popular mobile ad-hoc network routing protocols i.e. Landmark Ad-hoc Routing Protocol (LANMAR), Location Aided Routing scheme 1 (LAR1), Dynamic MANET On-Demand (DYMO) and Zone Routing Protocol (ZRP) in variable pause time. We used well known network simulator QualNet 5.0 from scalable networks to evaluate the performance of these protocols. The performance analysis is based on different network metrics such as average jitter, packet delivery ratio, average end-to-end delay and throughput.
